[1] The frame members 12 and 13 constitute the left and right outer frames of the front grill 11, and the light guides 14 and 15 are accommodated in the frame members 12 and 13, respectively. The light guides 14 and 15 are not arranged on the front side or the rear side of the front grill 11.
Therefore, since each frame member 12 and 13 and each light guide 14 and 15 (light emitting member) do not block each grill opening 11b of the front grill 11, the air permeability of the front grill 11 (decorated member) is impaired. I can't.
Therefore, in the vehicular lighting device 10, the function of taking outside air into the engine room, which is the original purpose of the front grill 11, is not impaired, and the cooling of the engine is not adversely affected.

[2] The light emitting surfaces 14a and 15a of the light guides 14 and 15 (light emitting members) are arranged along the shape of the left and right outer edge portions of the front grill 11 (decorated member).
For this reason, the left and right outer edges of the front grill 11 are particularly brightly and indirectly illuminated by the radiated light from the light emitting surfaces 14a and 15a of the light guides 14 and 15, and the left and right outer edges of the front grill 11 can be conspicuous even at night. Thus, the design of the front grille 11 that is built in consideration of the appearance of the daytime can be used at night.
